ID 343906 - When scanning for versions of a clip, Nuke Studio will hang at 100% complete

When scanning for new versions of a clip, the progress bar will quickly reach 100% but Nuke Studio will then hang, and may become unresponsive, before finishing the scan.

Customer reported version
nuke.11.1v2

Steps to reproduce

1) Open Nuke Studio.

2) Import a clip (File > Import Files...) that has multiple different versions. In this example I have used a clip with 39 new versions.

3) Scan for all versions of the clip by right clicking the clip in the Project Bin > Version > Scan For Version.

4) Notice that the progress bar will quickly reach 100% but Nuke Studio will then hang before finishing the scan.
